ABSTRACT
Tumors originating in the parapharyngeal space are rare. Eighty percent of the parapharyngeal space neoplasms are benign, and 20% are malignant. The most frequent tumours of this localization are those of salivary origin followed by neurogenic tumor and in third place the paragangliomas. This paper presents three representative cases of parapharyngeal space neoplasms. The literature is reviewed.

We present the case of a localized monostotic fibrous dysplasia in the frontal sinus with orbital extension and persistency after the first surgery; it had to be operated again with a fronto-orbitary reconstruction. The fibrous dysplasia is a rare bony alteration with transformation of the healthy bony tissue for a disestructuredone. Its etiology is unknown and can be associated to different syndromes, such as Albright's Disease. Its treatment is surgical, but presents a high percentage of recurrence, this is the xenson why it needs a close follow up.

We report in this work the casual find of two bilateral and symmetrical cystic images on the apex petrosus, asymptomatic and with periodic controls. In the review of the literature we haven't found another case of this entity. The differential diagnosis of this pathology is showed. We expose the most characteristic imagings.

Los osteosarcomas son tumores osteoides malignos poco frecuentes en cabeza y cuello. Suelen aparecer a nivel maxilar y mandibular, con escasa tendencia a la metástasis a distancia pero con gran recurrencia local. En este trabajo presentamos un caso en una localización más infrecuente, la región etmoido-orbital y base de cráneo; se trata de un osteosarcoma de gran tamaño, bien diferenciado con áreas que semejan la displasia fibrosa.Presentamos el caso clínico y revisamos la literatura (AU)

Sarcomatoid carcinoma of the upper aerodigestive tract is an unusual neoplasm with differential cellular differentiation. Microscopically, sarcomatoid carcinomas have an element of squamous-cell carcinoma and a pleomorphic sarcoma-like component, which may simulate granulation tissue, malignant fibrous histiocytoma, osteosarcoma, or malignant giant-cell tumor of soft tissues.

OBJECTIVE: To determine the diagnosis and treatment of a retropharyngeal hematoma. MATERIAL AND METHODS: The authors report a case of retropharyngeal hematoma associated with increased intrathoracic pressure caused by coughing. DISCUSSION: Retropharyngeal hematomas are usually spontaneously resorbed so the treatment is surveillance. Surgical drainage may be necessary. The causes, clinical manifestations, diagnosis, and surgical indications are reviewed.

INTRODUCTION: To accurate the diagnosis and treatment of retropharyngeal hematoma. MATERIAL AND METHODS: The authors show a case of retropharyngeal hematoma that appears just after a difficult and urgent orotracheal intubation. DISCUSSION: The retropharyngeal hematomas use to be spontaneously uptaken so that treatment may be observation. Sometimes, a surgical drainage is needed. Etiology, clinical signs, diagnosis and surgical indications are reviewed.
